Ridesizer is the world's first kids bike sizing tool that helps you choose the perfect bike for your child and tells you how long it will last.

Try it out now: RideSizer!

How do I pick the right size?

We recommend using the balance bike method when teaching your child to ride a bike, but understand all children learn differently. 
Here are the compatible training wheels recommendations: 16” and 20” Small Ethos: Compatible Training Wheels 
20” Small AIROS: Compatible Training Wheels+ Axle Extender (you will bend the support arms inward upon installation)

 

Can I use Training Wheels

All in-stock bikes typically arrive in 2-5 business days. Bikes are typically shipped via Fedex
 


When can I expect my order?

Set up time for our 16" or 20" bikes is about 5 minutes or so. Our 24" takes a bit longer as you have to install the front wheel.  All tools needed come with the bike. Here are a few assembly previews for you to check out:

16in bikes = install pedals and handlebars (5 min)
20in bikes = install pedals and handlebars (5 min)
24in bikes = install pedals, handlebars, front wheel (10 min)
